Which activity is most effective in improving bone density for someone with osteoporosis?

• A. Swimming
• B. Range-of-motion exercises
• C. Aerobics
• D. Walking

Answer: (D)

Bones respond to the stress placed on them. When bones are subjected to weight-bearing loading, the cells responsible for building bone (osteoblasts) are stimulated to strengthen the skeleton. Walking provides axial, weight-bearing stress to the spine, hips, and legs, which helps maintain or improve bone density. It’s also safe and practical for many people with osteoporosis, and it supports balance to reduce fall risk. In contrast, swimming is non-weight-bearing, so it doesn’t load the bones enough to meaningfully increase density. Range-of-motion exercises are helpful for mobility but provide minimal stimulus to bone remodeling, and even aerobics that are low-impact don’t load the bones as effectively as walking. Therefore, among these options, walking is the most effective for improving bone density in osteoporosis.
